FREDERICK HAUSER,' OF SAN FRANCISCO, CALIF ORNIAT WINDOW.

Application filed February 23, 1921. SerialNo. 447,031.

To all 'Il.]I07I2- it may concern:

- Be it known that I, FREDERICK Hansen, a (lfiZelLof the United States,residing at San F rancisco, in th county of San Francisco and State of California, have invented new and useful Tmproyements in Windows, of which the following is a specification.

The present invention relates to window construction and more particularly to improvements in apparatus for mounting window sashes so that they will be reversible and both sides thereof may be easily washed and cleaned from the inside of a: room or building.

The primary object of the invention is to simplify the construction and operation of reversible windows and to provide for simultaneously reversing the sashes of a multi-sash window, whereby in operating one of the sashes of such a window to reverse the same all of said sashes will be likewise reversed, the reversing action being such that it may be easily and quickly effected and causes the sashes to be so dis posed that ready and easy access thereto for washing, may be had.

Another object of the invention is to provide reversing apparatus of such a nature that it may be easily attached to and used in connection with standard sash and frame construction without necessitating any material changes in the construction of said sashes and frames, thus making ossible an inexpensive conversion of the or inary window into the reversible window of this invention; 1

The invention possesses other advantages and features some of-which, with the foregoing will be set forth at length in the following description where I shall outline in full that form of the invention which I have selected for illustration in the drawings ac- 'companying and forming a part of the pres- In said drawlngs I have I Figure 2 is a vertical sectional view thru a window frame showing the sashes and apparatusof this invention in side elevation and in open position.

Figure 3 is a view similar to Figure 2 but showing the sashes reversed and broken in part.

Figure 4 is an enlarged fragmentary side elevation of the upper sash hinge shown partly in section. V

Figure 5 is a View of the hinge similar to Figure 4 but taken from the outside of, the window frame. I

Figure 6 is a sectional View on line 66 of Figure 5.

F igure 7 is asectional view taken on line 77 of Figure 1.

Referring to the preferred embodiment of the invention as shown in the accompanying drawings, the window frame 1, having the customary vertical slide grooves 2, supports upper and lower sashes 3 and 4 respectively. Each sash has supporting arms 5 pivoted as at 6 to the side bars 7 thereof and as at 8 to plates 9 secured to the window frame 1, below the pivots 6. The pivots 6 are located between the upper ends and points centrally of the upper and lower ends of the bars 7 but nearer to the central points. The pivots 8 are located at points adjacent to which the lower ends of the sashes rest when the sashes are closed.

Both sashes are hingedly connected at their upper ends with sliding supports 10 which supports are mounted in the grooves 2 of the window frame. The upper ends of these supports 10 carry extensible memhers 11 held in place by screws 12 working in slots 13 in the members 10. Pivoted at one end to each of the extensible members as at 14: is a. hinge plate 15. The plates 15 are pivoted as at 16 to plates 17 fixed to the sides of the bars 7 of the upper sash.

The plates 15 areprovided with slots or notches 19 in which stop members 20 extend, said members 20 being carried on the extensible members 11. These stops engage with opposite ends of the slots or notches and limit the movement of the hinge plates in both directions. The plates 17 are provided with outwardly directed lugs, 21 which lie in the path of the lower edges of the hinge plates 15 at such angles as to cause the upper sash to be forced outwardly when said lugs are engaged by said hinge plates and the latter are moved on their pivots.

Fixed to the members 10 adjacent to their lower ends are forwardly projecting plates 22 and the outer ends of these plates are pivoted as at 23 to plates 24, fastened in any suitable manner, to the outer sides of the bars 7 of the lower sash The bars 7 of /the sashes have portions '25 on their outer edges which portions are arranged to enage shoulders 26 on the frame 1. The ower ed of the upper sash has a depending weat er strip 2 adapted to overlie the outer face of the upper part of the lower sash.

Operation.

To open the sashes the lower sash is' pushed outwardly. The lower sash turns on the pivots 6 and 23 and the arms 5 for this larly disposed as hereinbefore described,

the downward pull on the hinge plates 15 first causes a pivotal movement of these plates such that the upper sash wi]1"be 'forced downward and by reason of the arms 5 therefor will swing outwardly; The plates 15 move or rock on the pivot 14 only slight- 1y, but sufficient to start the upper sash on its outward movement. When the stops 20 engage the rear ends of the-slots or notches 19 the plates 15 are prevented from further movement on their pivots 14 and remain stationary while the upper sash turns'on the pivots 16, upon continued outward movement of the lower sash. It will thus be seen that both sashes may be moved to any extent desired by pushing outwardly on the lower sash. 7/

To reverse the sashesi for exam 1e, from the position shown in igure 2, t e upper ed e of the lower sash may be grasped and pu ed downwardl This moves the membars 10' downwar ly and ca-usesthe upper ends of the sashes to be moved downward while the lower ends thereof move out and upwardly in an are. This reverses the windows so as to brin them into a dproximately a 45 angle, with the outer si es of the sashes uppermost and in, po-

sition to be readily reached in the washing and cleaning thereof, (see Figure 3).

' 1 To move the sashes back into normal position the normally upper edge of the lower sash is lifted upwardly until the lower edge is in position to be conveniently grasped and pulled inwardly to complete the closin operation. The movement of the lower sas is followed by similar movement of the upper sash.

By the peculiar combination of the sliding supporting members to whichthe sashes are hinged at their upper edges and the arms 5 pivoted to the sashes and window frame, the operation of the windows is made comparatively easy and convenient. The lugs 21 and plates 15 are arranged so as to prevent sticking or jamming of the window in starting the opening or reversing operation.

A window comprising a frame,-a member movable up and down upon said frame, a sash, anarm pivoted to a mediate portion of a side of the sash and pivoted to the frame, a hinge connecting the sash with said movablemember, another sash, an arm pivoted to said sash and the frame, a hinge plate pivoted to said member and the lastnamed sash which plate on initial movement of said member when the sashes are in closed position, will move on its pivotal connection with the member and a stop for limiting such movement of said plate.
